Is the Left just being targetted or is the Left also sincere in its fight. Tough question. Consider two issues :- 1) The Left's stand on the Nuclear deal. They fought tooth and nail, warned the Govt of serious consequences (read withdrawal of support), yet they did nothing but quietly allowed steps to be taken by the Govt. No judgement on this issue, but just an assessment on the Left's stand.
2) The recent view of the Left regarding increase in fuel prices. They warned the Govt again of serious consequences. Yet, the Govt policy did not change one bit.
May be people are giving the Left more margin than they actually deserve.
